fix(ui): use folds Text priority instead of raw opacity (native-cinny nit)

Replaced raw style={{ opacity: N }} de-emphasis on folds <Text> with the
`priority` prop across search, schedule, profile, and tray UI. Left the cases
that aren't Text-priority candidates (an Icon opacity, a Box-row opacity, and a
Text with an explicit color token).
